Natco Lake

Natco Lake is a lake in Keansburg, Monmouth County, New Jersey. It was a man-made body of water located on the site of a former clay brick mine, and its name is an acronym for the National Fireproofing Company, which mined the area for clay mud during the 1930s. It was created by accident, when an attempt to drain the lake by connecting it to Thorne's Creek with a ditch led to the tidal creek filling the mine with sea water. Natco sold off the lake and its surrounding property, and Natco Park was established in 1978. The untouched northern section is now home to homeless encampments.
